| pubmed-article:6625135 | pubmed:abstractText | Comparison of a linear analogue scale on paper and a computerised audiovisual analogue scale presented on a visual display unit is described. Pain was assessed postoperatively in 109 patients and anxiety pre-operatively in 146 patients. Results show a strong correlation between gradings obtained using the two methods, indicating the computerised method is as reliable as the conventional one. | lld:pubmed |
